1. An apparatus for manufacturing a carbon block filter, the apparatus comprising:
a mold having an inner space;
a heater coupled to the mold to heat the mold;
a material injection unit configured to inject a material to the mold heated by the heater; and
a material pressing unit configured to press the material,
wherein the material includes a powdered activated carbon and a binder, and
wherein the heater heats the mold at a temperature at which the binder cross-links the activated carbon particles to each other prior to the material being injected to the mold,
wherein the apparatus further comprises a transferring unit extending along a circumference of a closed figure to transfer the mold in one direction,
wherein each of the material injection unit and the material pressing unit is installed to perform a function thereof on the mold transferred on the transferring unit,
wherein the material injection unit and the material pressing unit are disposed adjacent to each other in an order with respect to a direction in which the mold is transferred, and
wherein a first distance of transferring the mold from the material pressing unit to a location where a thermally treated filter is separated from the mold is spaced in correspondence to a time required for thermally treating the material, the first distance is longer than a second distance, wherein the second distance corresponds to a distance of transferring the mold from the material injection unit to the material pressing unit; or wherein a first distance of transferring mold from the material injection unit to the material pressing unit is spaced in correspondence to a time required for thermally treating the material, the first distance is longer than a second distance, wherein the second distance corresponds to a distance of transferring the mold from the material pressing unit to a location where a thermally treated filter is separated from the mold.
